Question

我在Struts2-fullhibercorecore-plugin的帮助下链接Struts2和hibernate。

不幸的是我收到了这个错误。我发现问题可能在我的类路径上有hibernate版本。

这是我的pom.xml。 现在已经过编辑，效果很好：

这是错误：

有人可以看看我的pom说出那里有什么问题吗？

Answer 1

当一个库（即struts2-fullhibernatecore-plugin）针对一个版本的依赖项（即hibernate）进行编译但是它针对另一个版本运行时，会发生'NoSuchMethodError'。

从命令行运行以下命令：

mvn dependency:tree

然后看看struts2-fullhibernatecore-plugin期望的hibernate版本。

我猜你会发现struts2-fullhibernatecore-plugin期望某个版本的hibernate。但是，由于您在pom maven中明确定义了hibernate的版本，因此使用此版本。请参阅最接近的定义获胜策略here。

要修复，请将pom.xml中的hibernate版本更改为struts2-fullhibernatecore-plugin预期的版本。

java.lang.NoSuchMethodError：org.hibernate.SessionFactory.openSession（）Lorg / hibernate / classic / Session;
